none of the virtues of the hop. (Annals of Phil. p.194.) The 
virtues of the strobiles are extracted by boiling water, or alco- 
hol, or ether. The watery infusion has a pale straw-color, is 
rendered muddy by the mineral acids; alkalies deepen its 
color; it strikes an olive with sulphate of iron, is precipitated 
by alcohol, solution of superacetate of lead, nitrate of silver, 
and tartarized antimony, and when rubbed with magnesia or 
lime, a rod dipped in muriatic acid discovers the presence of 
ammonia. ‘The ethereal tincture, when evaporated in water, 
leaves a pellicle of greenish, intensely bitter resin, and de- 
posits some extractive. By distillation in water, hops yield a 
volatile, aromatic oil. From these experiments they appear 
to contain resin, extractive, volatile oil, tannin, an ammo- 
niacal salt, and what has been termed the bitter principle. 
Humvuuus Lurvuuvs is narcotic, tonic, diuretic, and, exter- 
nally applied, anodyne and discutient. Hops are said to pos- 
sess the power of procuring sleep in the delirium of fever, and 
in mania, when used as a pillow, and owing to this effect 
having been confirmed in the case of King George the Third 
of England, their efficacy as a general narcotic when intro- 
duced into the stomach has been investigated. Dr. Maton 
observed, that, besides allaying pain and producing sleep, the 
preparations of hops reduce the frequency of the pulse, and 
increase its firmness in a very direct manner. One drachm 
of the tincture and four grains of the extract given once in 
six hours. He found the extract exceedingly efficacious in 
allaying the pain of articular rheumatism, but subsequent ex- 
perience has not afforded sufficient proof of its utility as a 
sedative, and Dr. Bigsby’s experiments have lessened very 
much the confidence physicians were previously disposed to 
give to it. An ointment compounded with the powder of the 
hop and lard is recommended as an anodyne application to 
cancerous sores. A fomentation of it will certainly afford 
much relief in painful swellings and tumors. 7 
When administered internally, all the good effects of hops 
may be obtained by the use of Lupulin, which is best given 
in pills, in doses of six to ten grains, or in tincture in those 
of half adrachm to adrachm. The pills may be made by 
_ simply rubbing the powder in a warm mortar till it acquires 
the consistence of a ductile mass, and then moulding it into 
the proper shape. Lupulin may be likewise substituted for 
the hops in poultices, ointments, &c., with much advantage. 
_ The principal consumption of hops is in the manufacture 
of malt liquors, to which they communicate the bitter flavor
